Definitions
- the present invention relates to dressings and in particular dressing for covering limb extremities, method of treating wounds and pressure sores therewith and dressing material blanks from which the dressings can be formed.
- Conventional dressings for the treatment of wounds or pressure sores are essentially flat dressings which are only sufficiently absorbent to absorb wound exudate and conformable to be applied to extensive flat or curved areas of the body. These flat dressings, however, are not very suitable for use on protruding areas of the body such as elbows, heels and the tops of fingers or toes.
- United States Patent No. 3937218 discloses protective cushion pads for prevention of pressure sores on patients who are confined to bed for extended periods.
- the pads can be used in the treatment of wounds as a wound or pressure sore dressing or that the pads are aborbent or that such pads are extensible to enable them to be used as conformable absorbent wound dressings.
- Conformable absorbent dressings have now been found which have a shape which is suitable for treating wounds or pressure sores on protruding areas or parts of the body and which can easily be formed from a flat dressing blank.
- a conformable wound dressing of concavo-convex shape comprising a body facing layer of an apertured elastomeric material having a concave wound contacting surface, an outer layer of a bacteria impermeable, moisture vapour transmitting, elastomeric film having an outwardly facing convex surface and an extensible intermediate layer of an absorbent material.
- a dressing of the invention means a dressing which is capable following the contours of the body and also the movement of the skin at areas to which it has been applied.
- the concavo-convex shape or cup-like shape of the dressing of the invention renders it highly suitable for use on a protruding parts of the body such as an elbow, heel, toe or finger (includes thumb).
- protruding areas or parts of the body are prone to injury by knocks, abrasion, pressure or a combination of two of these conditions. Such injury may cause a wound or a pressure sore on the protruding area.
- the conformable and absorbent nature of the dressings of the invention renders them highly suitable for use on such wounds and pressure sores.
- One favoured dressing of the invention is therefore a wound dressing.
- Another favoured dressing of the invention is therefore a pressure sore dressing.
- the size and shape of the dressing can be adapted to the protruded area to which the dressing is to be applied.
- Preferred dressings of the invention are adapted to be applied to the heel or elbow.
- the absorbent material used in dressings of the invention will be extensible, aptly soft and flexible and preferably also resilient to provide the dressing with a cushioning property.
- Suitable absorbent materials of this type include absorbent polymer foam layers or sheets and absorbent non-woven fabrics containing bonded high loft fibres and absorbent fibres (if not high loft fibres) such as cellulosic fibres for example cotton or viscose rayon fibres .
- Favoured absorbent materials for use in the invention are absorbent foam layers such as open celled foam layers of an elastomeric polymer such as polyurethane.
- Preferred absorbent materials are absorbent foam layers of a hydrophilic polymer such as hydrophilic polyurethane.
- Hydrophilic polymer foam layers can provide the dressing with a high absorbent capacity.
- Suitable hydrophilic polyurethane foams for use in the invention are disclosed in European Patent Application No. 0299122 and European Patent No. 0059049.
- the dressing of the invention can advantageously comprise a non-adherent wound facing layer.
- Suitable non-adherent layers include apertured elastomeric layers such as flexible apertured films and flexible nets having a non fibrous surface.
- Favoured layers of this type are nets or apertured films or elastomers.
- Preferred wound facing layers however are nets of an elastomer such as thermoplastic polyurethane and A-B-A type block copolymers where A is polystyrene and B is polybutadiene or polyisoprene .
- a wound facing net of elastomer can render the dressing of the invention highly conformable to wound or sore surfaces.
- Suitable non-adherent wound facing layers for use in the invention are disclosed in the hereinbefore mentioned European Patent No. 0059049.
- the outer layer of the dressing of the invention can comprise a flexible continuous film to provide a barrier to the penetration of aqueous liquids and bacteria, ie. a bacteria and aqueous liquid impermeable layer .
- the barrier film is also moisture vapour permeable to allow evaporation of aqueous fluid under the dressing.
- Favoured barrier films of this type for use in the invention include flexible films of polyurethane, such as thermoplastic polyether-polyurethane , blends thereof with an incompatible polymer such as polystyrene, polyether-ester and polyether ester block copolymers and hydrophilic polyurethane films.
- Suitable barrier films for use in the invention are disclosed in the hereinbefore mentioned European Patent No. 0059049.
- Suitable hydrophilic polyurethane films for use in the invention are disclosed in European Patent No. 0123465.
- Favoured absorbent materials for use in the invention comprise a laminate of a non-adherent wound facing layer, an intermediate absorbent layer and an outer continuous film barrier layer which is a bacteria and aqueous liquid impermeable layer.
- the non-adherent wound facing layer comprises a net or apertured film of elastomer
- the absorbent layer comprises a flexible hydrophilic polymer such as hydrophilic polyurethane foam
- the outer continuous film barrier layer is moisture vapour permeable layer.
- a dressing comprising the favoured and preferred laminate absorbent materials hereinbefore mentioned has a number of advantages over a conventional dressing.
- the conformable nature of the dressing allows it to maintain close contact to a body surface to which it is applied thereby inhibiting any pooling of non-absorbed fluid from an exuding wound or pressure sore.
- the absorbent capacity of the dressing absorbs large amounts of exudate from an exuding wound or sore.
- the barrier properties of the dressing inhibits penetration of pathogenic bacteria or aqueous liquid through the dressing to the wound or sore site and can also inhibit egress of exudate from the wound or sore site to the outer surface of the dressing.
- the resilient nature of the dressing allows the dressing to cushion a wound or sore area against pressure and also allows the dressing to quickly recover its initial thickness after being compressed.
- the thickness of a dressing of the invention can suitable be at least 0.5mm and can preferably be at least 1mm.
- the thickness of the dressing can suitably also be not greater than 20mm and can preferably be not greater than 15mm. Typically a thickness of 1mm to
- the moisture vapour permeability properties of the dressing can allow absorbed exudate to evaporate thereby increasing absorbent capacity of the dressing. Such permeability properties will also allow intact skin under the dressing to breathe thereby inhibiting maceration thereof by the build up of moisture in the skin.
- the moisture vapour transmission rate of the dressing should be sufficiently high to allow these advantages to occur but sufficiently low to prevent the wound drying out.
- the moisture vapour transmission rate (mvtr) of the dressing can suitably be greater than 300gm -2 and can preferably be greater than ⁇ OOg ⁇ r 2 24h _1 at 100 to 20% relative humidity difference and at 37°c.
- the moisture vapour transmission rate values hereinafter are abbreviated to g ⁇ r 2 .
- the MVTR of the dressing can suitably be less than 3000g ⁇ r 2 and can preferably be less than 2500g ⁇ r 2 .
- the MVTR can be at least 2500gm -2 and may be less than 14000g ⁇ r 2 .
- a dressing with these MVTR properties can allow moist healing of a wound or sore and when suitably high can provide a soothing cooling environment which relieves pain.
- Moisture vapour transmission rate (MVTR) of the dressing material by the payne cup method.
- discs of the dressing material that is a laminate comprising for example a net, foam and outer barrier layer, to be tested are clamped over Payne permeability cups (flanged metals cups) using sealing rings and screw clamps.
- the exposed surface of the test sample is 10cm .
- Each cup contains approximately 10ml of distilled water.
- the cups are removed after 24 hours, allowed to cool for 20 minutes and reweighed.
- the MVTR of the test material is calculated from the weight loss and expressed in units of grams of weight per square metre per 24 hours, at 37°c at 100-10% relative humidity difference.
- the combination of the MVTR and non-adherent properties of the dressing allow the dressing to be left on the wound or sore site until healed and then removed without disrupting the healed wound or sore surface.
- the present invention provides a dressing material in the form of a blank having lobate configuration.
- the dressing material comprise a single blank of the material having two lobes joined together by a common neck region.
- the concavo-convex shape is formed by folding the blank at the neck region and adhering the edges of each lobe which are adjacent the folded neck region to each other. In adhering these edges together the blank is maintained in the form of a concavo-convex shape .
- the dressing material may be separate pieces or blanks of the material each of a lobate configuration. On joining the two pieces together at a part of the edge region the composite structure deforms to assume a concavo-convex shape.
- edges of the material can be joined by any suitable convenient method. Suitable methods include adhesive bonding, heat sealing and fixing by adhesive tape .
- a preferred embodiment of joining the edges comprises a heat sealing method such as an impulse induction or radio frequency heat sealing method.
- edges of the sides are abutted together to provide a substantially smooth or even join.
- the concavo-convex shape of a dressing of the invention comprising a laminate can conveniently be formed by abutting a first edge of the laminate with a second edge of the laminate and sealing the edges together along a curved line.
- Each of the edges will normally be an edge of a blank formed by a single sheet of the laminate.
- Figure 1 is a plan view of a blank of the invention
- Figure 2 is a plan view of a different blank of the invention
- Figure 3 is a perspective view of a dressing of the invention formed from the blank shown in Figure 1
- Figure 4 is an enlarged version of an edge portion of Figure 3.
- Figure 1 shows a blank 1 of the invention made of a soft, flexible, absorbent material with the wound facing surface uppermost. Blank 1 has two portions 2, 3 connected by neck portion 4.
- portions 2, 3 have a similar bulbous shape and size. Portions 2, 3 have each rounded ends 5 and a pair of straight sides 6, 7 adjacent to neck portion 4.
- Blank 1 can be folded (inwardly of the wound facing surface) about neck portion 4 and opposed sides 6, 7 of portions 2, 3 joined together to form a concavo-convex shaped dressing.
- Portion 2 of Blank 1 has re-entrant cutout portions 8 either side of neck portion to compensate for the thickness of the absorbent material.
- Figure 2 shows a blank 9 similar to that shown in Figure 1 having two portions 10 and 11 connected by a neck portion 12.
- Portions 10 and 11 have a similar circular shape and size. Both these portions have rounded ends 13 and 14 and a pair of sides 15 and 16 adjacent to the neck portion. However, sides 15 and 16 are curved sides instead of straight sides in the blank of Figure 1.
- the blank portions 2, 3 can be adapted in size and shape to the type of dressing which it will form, for example, in a blank for forming a heel dressing portion 2 which is adapted to cover the back and side of the heel could be wider than that of portion 3 which is adapted to cover the bottom of the heel.
- Figure 3 shows a dressing of the invention formed from the blank of Figure 1.
- Dressing 17 has a flattened concavo-convex or cup shape.
- Dressing 17 has folded peripheral region 18 and two outwardly extending skirts 19, 20 which are joined at two side regions 21, 22.
- the angle subtended by the skirts shown in Figure 2 is less 90°.
- Such an angle can be adapted to the type of dressing eg. an elbow dressing is likely to have a much higher peripheral angle than a finger dressing.
- Figure 4 is an enlarged version of the edge of the skirt 19 of dressing 17 showing the absorbent material 23 of dressing 17.
- Absorbent material 23 has wound facing layer 24, absorbent layer 25 and an outer layer 26.
- the present invention provides a method of treating a wound on a protruding part of the body which comprises applying a dressing of the invention over the protruding part to contact the surface of the wound thereon.
- the present invention provides a method of treating a pressure sore on a protruding part of the body which comprises applying a dressing of the invention over the protruding part to contact the surface of the pressure sore thereon.
- the wound contacting surface of the dressing makes contact with the surface of the wound or sore on the protruded area.
- the dressing can be maintained on the protruded area by any suitable means.
- suitable means include a bandage such as tubular bandage, an adhesive tape or an adhesive coating on the wound facing surface of the dressing.
- Such an adhesive coating can extend over a part or whole of the wound facing surface of the dressing, in favoured dressing of the invention the adheisve coating is located on wound facing surface thereof on the peripheral area of the lobate regions of the dressings.
- Such dressings advantageously have a wound contacting area free when the dressing comprises an apertured layer such as a net or apertured film.
- the adhesive coating can advantageously be on the unapertured area thereof to render the adhesive layer moisture vapour permeable.
- the adhesive used in the invetion will normally be a pressure senstive adhesive which is suitable for contact with skin.
- Suitable adhesive include polyvinyl alkylether, acrylate ester copolymer and polyurethane gel adhesives.
- Suitable polyvinyl alkylether in European Patent Nos. 35399 and 51935 and United Kingdom Patent No. 1280631.
- Apt adhesives of this type are polyvinyl ethyl ether adhesives and copolymers of 2 ethyl hexyl acrylate, butyl acrylate and acrylic acid.
- Suitable polyurethane gel adhesives are disclosed in European Patent 123465. Such gel adhesives advantageously have a low adhesion to wound and skin surfaces and therefore can be easily removed therefore without causing damage to the skin or the wound.
